Abstract

English

Seeing, at its simplest, is merely the registering of light and some reaction to it. Primate visual perception is not only a passive, feedforward absorption of information of the surrounding environment. While simple light sensitive creatures show purely stimulus driven light avoidance / attraction responses, our own visual system consists not only of low-level vision but of more complex mechanisms operating on the low-level output. It is the interpretation of what we see in the light of knowledge and experience about the world. Vision is therefore also influenced by intention, context and memory. These do not make their contribution late within the visual processing chain but rather affect all cortical processing of visual input.
